In microcontact printing, selective contact between the substrate and the micro- or nano-scale features on the stamp results in transfer of a molecular or fluid ink.  The proposed layered stamp alter layer optical properties.  Transmission of UV light generates a high-contrast image of the printing zone, a region of conformal contact between the patterned stamp and the impression surface. The clear visibility of the contact areas allows continuous (in-line) inspection of the printing process, and hence greater active control capabilities to meet rapidly increasing resolution demands of micro / nano printed substrates.
